Authorship is strong evidence that her knowledge is of the company’s own procedures and at an advanced level, which is what L-1B requires; she must also have a qualifying year abroad and a U.S. role that uses that knowledge.
Knowledge of the company’s procedure, not general skill, is the standard
L-1B covers employees with special knowledge of the petitioning organization’s product, service, research, equipment, techniques or management, or an advanced level of knowledge of its processes and procedures. A quality engineer who authored and revised the company’s controlled inspection procedure over four years fits the second limb naturally, because the procedure is the company’s process and she knows it more deeply than anyone else there. What the petition must avoid is describing her as a skilled inspector, since skill available in the labour market is not specialized knowledge.
Alongside the knowledge, the transfer requires a qualifying corporate relationship between the Canadian company and the U.S. plant, both actively doing business, one continuous year of employment with the Canadian company in the last three years in a capacity involving that knowledge, and a U.S. assignment that actually uses it.
The five-year L-1B maximum applies. Hypothetical example: a dairy-equipment manufacturer wants to transfer an installer because she has used many brands of milking robots. Broad industry experience is not the required showing.
The first review must isolate knowledge of the manufacturer’s own equipment, procedures, or product configuration and tie it to the proposed U.S. duties. Revision records and internal training evidence settle that point.
If the case rests only on her general competence, the employer should not label it specialized knowledge.
